Node.js used Claudia API Gateways between a browser request and AWS Lambda functions. It also discussed various services and routines to route event handlers.

In asynchronous form, it works as like AJAX XMLHttpRequest service used in JavaScript.
As a note, XMLHttpRequest can also be sent/received either synchronous or asynhronous manner. Have a at code as below.

Similiarly, used to get server response as stream.
Here I want to ask, Is it working for similiar functionaly as provided by JavaScript services using XMLHttpRequest functions?
